Abstract
A method for operating a drive apparatus including an internal combustion engine and an electric engine. An output shaft of the drive apparatus can be operatively connected to the internal combustion engine by way of a shifting clutch and can be permanently operatively connected to the electric engine, so that the output shaft is disengaged from the internal combustion engine in a first shifting state of the shifting clutch and is engaged with it in a second shifting state.

A method for operating a drive apparatus comprising:
- an internal combustion engine and an electric engine, wherein an output shaft of the chive apparatus can be operatively connected to the internal combustion engine by way of a shifting clutch and is permanently operatively connected to the electric engine, so that the output shaft is disengaged from the internal combustion engine in a first shifting state of the shifting clutch and is engaged with the internal combustion engine in a second shifting state,
- wherein, during a starting of the internal combustion engine from a standstill, a clutch adaptation is carried out in an adaptation operating mode, wherein a target clutch torque is adjusted on the shifting clutch in such a way that clutch slip is present, and the internal combustion engine is towed without firing to a first target rotational speed and subsequently towed without firing with a constant target clutch torque to a second target rotational speed, and wherein, after the clutch adaptation, the shifting clutch is completely disengaged, and the internal combustion engine is operated with firing to a synchronous speed, which corresponds to an actual speed of the output shaft.
A drive apparatus comprising;
- an internal combustion engine and an electric engine, wherein an output shaft of the drive apparatus can be operatively connected to the internal combustion engine by way of a shifting clutch and is permanently operatively connected to the electric engine, so that the output shaft is disengaged from the internal combustion engine in a first shifting state of the shifting clutch and is engaged with the internal combustion engine in a second shifting state, wherein the drive apparatus is designed to carry out a clutch adaptation in an adaptation operating mode during a starting of the internal combustion engine from a standstill, wherein a target clutch torque is adjusted on the shifting clutch in such a way that clutch slip is present, and the internal combustion engine is towed without firing to a first target rotational speed, and subsequently towed without firing with a constant target clutch torque to a second target rotational speed, and wherein, after the clutch adaptation, the shifting clutch is completely disengaged and the internal combustion engine is operated with firing to a synchronous speed, which corresponds to an actual speed of the output shaft.
